There's no hope." But I say to them, I said, "Did you ever think that our great Watergate president would leave office the way he did?" "No, I guess I didn't think that." I said, "Did you think that the Berlin Wall would come down so peacefully?" "No, I didn't think that would happen, yeah." I said, "Did you think Mandela would be president of South Africa?" "No, I didn't predict that." "Well, if you couldn't predict those three things, then don't be so confident that there's no hope." And I give them a bumper sticker. It says, "There's No Hope, But I May Be Wrong."

“A good song can only do good, and I am proud of the songs I have sung. I hope to be able to continue singing these songs for all who want to listen, Republicans, Democrats, and independents.”

“Shh. Listen to the sounds that surround you. Notice the pitches, the volume, the timbre, the many lines of counterpoint. As light taught Monet to paint, the earth may be teaching you music.”
